What is this FLAC to WAV converter?
A free, browser-based tool that converts FLAC audio to WAV. Add a file, preview it inline, and download the result. All processing happens locally in your browser, so your file is never uploaded and there is no watermark.
FLAC to WAV is decoding, not converting
A FLAC file already contains a complete lossless copy of the audio; turning it into WAV just unpacks that data into uncompressed PCM. No samples change in either direction, so the WAV sounds exactly like the FLAC, and you can go back at any time without losing anything. If a difference were audible, something else in the chain caused it.
What changes is size. Compression comes off, so expect the file to grow to roughly 1.7 to 2.5 times the FLAC: a 30MB FLAC track typically unpacks to somewhere between 50 and 75MB of WAV.
The gear and workflows that still insist on WAV
The usual reason for this conversion is a stubborn recipient. Older DAW versions and hardware samplers ignore FLAC, plenty of video editors only ingest WAV or AIFF on their timelines, and broadcast delivery specs frequently list WAV as the only accepted audio. Burning an audio CD is another classic case, since CD audio is uncompressed 44.1kHz 16-bit PCM and burning software wants WAV to work from.
Treat the WAV as a temporary working copy for that one tool. The FLAC stays the space-efficient archive; regenerate WAVs from it whenever the next legacy system asks.
How to use it
- Add a FLAC file on the left (drag & drop or click) — it shows an inline preview.
- Pick a quality preset (used only for lossy targets like MP3/M4A/OGG).
- Press “Convert & download” to get your WAV file. The first run downloads the ~30MB converter once.
Lossy vs lossless audio
WAV and FLAC are lossless — they preserve the original waveform exactly (FLAC is compressed, WAV is not). MP3, M4A (AAC) and OGG are lossy: they shrink the file by discarding inaudible detail, and the quality preset controls the bitrate. Converting a lossy file to a lossless format can't recover quality that was already lost. One special case: converting to M4A when the source is already AAC just repackages the container (a lossless remux) — instant and bit-exact.
